5 Claims.

fastener assembly, incorporating a continuous bead, to provide in saidslidera wing formation serving as an enclosing socket for said bead inconjunction with another wing of said slider serving as a channeledguideway for the spaced fastener elements carried on the stringers.

Further, it is an object of this invention to provide in a coveredslidefastener assembly incorporating a continuous beaded tape, for a slider,one of the wings of which is in the nature of a plurality of U-shapedchannels acting on, a substantial surface of the interlocking fastenerelements applied in the assembly and having for its other wing aplurality of opposing channels to form sockets substantially enclosingthe cover beads forming part of the assembly.

Specifically, it is an object of this invention to provide in a slidefastener assembly, wherein the stringer incorporating fastener elementshas at its edge a bead for covering the head of the fasteners forming acovered slide fastener assembly, to provide a slider, one of the wingsof which is in the nature of a channel substantially enclosing thebodies of the spaced fastener elements and the other wing of whichincorporates a pluralityv of spaced sockets serving to enclose andguidethe beads of the stringer serving as the cover portions for theheads of the fastener elements, such construction serving to providethrough the guiding action of the channels on the slider upon thecontinuous tape bead, for a medium whereby the fastener elementssuspended on the tapes are positivelydirected into the channels of theslider cooperating therewith.

These and other advantages, capabilities and features of the inventionwill appear from the subjoined detailed description of one specificembodiment thereof illustrated in the accompanying drawing, in whichFigure 1 is a perspective view of a slide fastener assemblyincorporating my slider.

Figure 2 is a perspective view of a preferred embodiment of my slider. I

view of a modified Referring to the reference characters in the drawing,numeral Ill represents a slider acting upon stringers of the charactershown and described in Letters Patent to David Silberman, 2,097 ,475,dated November 2, 1937, each comprising of a flexible tape l I having abody portion l2 extending in a horizontal plane, a bead formation I3 atone of its edges, and a bead formation [4 intermediate of its edges. Theintermediate bead formation. l4 carries depending therefrom spacedfastener elements l5, whose jaws l6 and I6 substantially surround andgrip the same. The end bead formation I3 is disposed over-and restsagainst the top face ll of the head l8 of the fastener element, whichfastener element incorporates the usual male and female locking ormeshing portions l9 and I9.

Referring in particular to the slider I 0, the formation and cooperationof which, with the stringers and particularly the cover bead l3 at theedges of such stringers, forms the essence of this invention; suchslider is formed of a channel shaped metallic stamping Y-shaped inconformation As indicated in the two modifications thereof shown herein,the lower wing section comprising diverging arms 20 and 20' which leadto a merging stem or arm 2|, the cross-section of the same beingsubstantially in the nature of a. U-.-shaped channel and servingrespectively at the diverging arms and the merging stem to surround thesides and lower portion of the respective fastener elements as separatedand then interlocked. f

As shown in Figures 1, 2 and 3, the slider is formed to provide anangularw-edge 22 between and defining the diverging channels 20 and 20',said wedge being integral with and forming'the inner side wall of therespective diverging channels. Integral with and extending inarcuate'formation for the length of .the wedge there is provided'on'upper wing section, arcuate arms or socket formations 23 and 23'adapted to enclose and act upon cover beads l3 at the edges of thetapes. A separable tab lug 24 comprising a longitudinally slotted bodyportion 25 having depending therefrom integral leg 26, is mountedbetween the walls defining the wedge 22 by welding or other fasteningmethod, so that theslider may be actuated for reciprocation'to separateinterlocking fastener members by pulling the tab lug or the ring tab 21carried on thehoriz ontal slot thereof.

As shown in Figures 4 and 5, the slider-is of length with the channeledwalls thereof serving to enclose the bottom and sides of the fastenerelements; there being mounted as by welding or riveting or the like, atab lub 24 having disposed on opposite sides of its leg 26 wings 23 and23' for surrounding and acting on the edge beads l3 as the slider isreciprocated.

In operation, the slider as it reciprocates functions as follows: Thewalls defining the diverging channels 20 and 20' leading to the mergingchannel 2| of the lower wing surround the side walls and bottom of thefastener elements and act thereupon, While the arcuate arms or socketformations 23 and 23' of the upper wing carried on the wedge in theembodiment shown in Figures 1 to 3 and upon the tab lug in themodification shown in Figures 4 and 5, enclose the beaded edges l3 ofthe tapes and act as sockets and guides therefor.

The enclosing and guiding function of the arcuate arms or socketformations 23 and 23 acting upon the edge beads l3 provides theadvantage that the passage of the spaced fastener elements through theslider as the latter is reciprocated, is controlled by the continuousbeads l3 enclosed within the arcuate arms or socket formations, thefastener elements being supported and maintained 'in proper alignmentfor entrance particularly, and thereafter passage through the slider.

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims."

I claim:

1. In a slide fastener assembly, in combination, opposing stringers,each provided with a series of spaced fastener elements and a continuousbead extending longitudinally thereof, and a slider cooperating withsaidstringers, said slider beingprovided with a plurality of channeledformations to accommodate the fastener elements of the stringers, andbeing provided with socket formations closely following the contour ofthe beads of the stringers for accommodating the beads, said slider uponreciprocation serving to interlock and separate the fastener elements,and the beads upon passing through the sockets of the slider serving asa guide for the fastener elements entering the channeled formation.

2. In a slide fastener assembly, in combination, opposing stringers,each provided with a series of spaced fastener elements and a continuousbead:

extending longitudinally thereof, and a slider cooperating with saidstringers, said slider having opposing wings, one of which wings isprovided with channeled formations to accommodate the fastener elementsof the stringers, and the other of which wings is provided with socketformations closely following the contour of the beads of the stringersfor accommodating the beads, the slider upon reciprocation serving tointerlock and separate the fastener elements and the beads upon passingthrough the socket formations, serving as a guide for the fastenerelements entering into the channeled formations.

3. In a slide fastener assembly, in combination, opposing stringers,each provided with a series of spaced fastener elements and a continuousbead extending longitudinally thereof adjacent the fastener elements,and a slider cooperating with said stringers, said slider havingopposing wings, one of which wings is provided with channeled formationsto accommodate the fastener elements of the stringers, and the other ofwhich wings is provided with socket formations closely following thecontour of the beads of the stringers for accommodating the beads.

4.
